I've been a bit concerned for a while about DSS not wanting to get rid of stuff and with Christmas (loads of new stuff) DH has had to admit that there does seem to be an issue. (Previously he has always said I am over-reacting as DSS's mum is a terrible hoarder). You literally cannot get into DSS's room ATM, and DH tried to sort through stuff with him but DSS doesn't want to part with anything, including broken toys, stuff he never plays with etc.
We've tried asking him to donate to charity (agrees with principle, just doesn't want to donate anything). Now he wants to 'give' some of the stuff to DS (so it can be stored in DS's room - DS doesn't want the stuff) and he's asking DH to build shelves in his wardrobe. I think that will just delay sorting out the problem and have suggested that DH get say, 20 of the most broken/age inappropriate toys and say DSS can only keep 10 of them. DH's suggestion is to say that he can take stuff he won't get rid of back to his Mum's. (Which is just bound to cause confrontation as it was only just before Christmas that she was off-loading old school projects on to us as her mother had told her she had to get rid!)
Any ideas?
